JOHN TESSEYMAN, OF CEICAG-G, ILLINOIS, TO RELIABLE EATLVIAY EQUTPMEHT COMPANY, OF CHICAGO, ILLINGTS, A CORPORATION OF ILLINOIS;

UNCOUPLING nnvron.

Application filed April 1,

To all whom it may concern Be it known that 1, JOHN E. TnssnYMAN, a citizen of the United States, residing in Chicago, in the county 01 Cook and State of Illinois, have invented a new and useful Improvement in Uncoupling Devices, of which the following is a specification.

his invention relates to uncoupling devices for car couplings and has for an object to provide a simple and eihcient uncoupling device embodying in its construction a pin operating connection between the uncoupling lever and the locking pin of the car coupling, which connection permits both longitudinal and lateral movement of the car coupling without danger of being disengaged from its connected parts, with the result that operative relations of the parts are maintained regardless of displacements of the coupling. The invention is further characterized by an entire adaptability to standard uncoupling levers and standard couplings and may be quickly applied, without any change in the construction oi these standard parts.

In addition to the general objects recited above, the invention has for further objects such other improvements or advantages in construct-ion and operation as may be found to obtain in the structures and devices hereinafterdescribed or claimed.

In the accompanying drawings forming part of thisspeciiication and showing, for purposes of exemplification, a preferred form and manner in which the invention may embodied and practiced, but without limiting the claimed invention specifically to such illustrative instance or instances 2-" Figure 1 is a fragmentary sectional view of the end of a railway car showing the application of an uncoupling device constructed in accordance with the improvements of the present invention;

Fig. 2 is a perspective View of the uncoupling device; and

Fig. 8 is a detailed top plan view of one of the members of the uncoupling device.

The same characters of reference designate the same parts in each of the several views of the drawings.

In the illustrated embodiment of the invention, the end sill of a railway car is indicated at 11 and a car coupling is indicated at 12, said coupling being of a standard type provided with a locking pin or block lifting connection between ing the pin-lifting connection.

1922. Serial No, 548,600.

13, which, when lifted, releases the coupling 12 and permits it to uncouple from a companioncoupling carried by an adjacent car. The coupling pin 13 is provided at its upper end with an eye 14 which receives one end of the pin-lifting connection, as will be hereinafter set forth.

Bolted to the car end, above the end sill 11, is a bracket 15, in which is rotatably supported the shaft 16 of a standard uncoupling lever. The said uncoupling lever is provided at its inner end with an arm 17 which extends longitudinally of the car and outwardly from the end sill over the pin '13 01 the coupling; and said lever is further provided at its outer end with the usual handle (not shown) which is operated in a counter-clockwise direction, as viewed in Fig. 1, to lift the outer end of the arm 17 and to effect the uncoupling operation. At its outer end, the arm 17 is provided with an eye 18 which receives the upper end of the pin-lifting connection.

In accordance'with the invention, the pin the uncoupling arm 17 and the pin 13 is constituted of a pair of members 19, 20 connected together so as to have relative swinging movements in all directions in addition to relative sliding movements, with the result that the connection may readily accommodate itself to either lateral, longitudinal or vertical displacements ot the coupling 12 without straining or disturbing the operative relations of the parts of the uncoupling assembly. For this purpose, the members 19, 20 are formed at their connected ends with closed loops 21 preferably elliptical in shape and providing similarly-shaped eyes 22, the loop 21 of each member being inserted in the eye 22 01" the other, as shown. With this construction, the connected members 19, 20 may not only move'freely toward each other, i, e.,vertically, but are also capable of practically universal movement with respect to each other.

At their respective upper and lower ends the members 19, 20 are 'formed with hooks 23 and 2 1 for insertion into the eyes 18 and 14 of the arm 17 and the pin 13, in apply- As shown, the hooks 2 3 and 2% are respectively formed with rebent portions 25 and 26 that extend backwardly of the main portions of the hooks and across the parts with which said hooks are connected, to prevent disengagement of the hooks from their connected parts, during swinging or other movement of the members 19, 20.

The invention as hereinabove set forth is embodied in a particular form of construction, but may be variously embodied within the scope of the claims hereinafter made.

I claim:

1. An uncoupling device comprising two members formed of: bent rod 0t like shape and size, each rod having one end bent to provide an open scroll-like hook and having the other: enl bent to form a closed elongated. loop, the elongated loops of the two members being loosely linked with each other.

2; An 1111((Hl1ilil'lg device having two members formed of. bent rods, each rod havingone end. bent to provide a verticallyand a laterally extending open hook and having the other, end rebent upon itself to provide an elongated closed loop, the. closed loop portions of'said rods being loosely connected to. each other.

3. An uncoupling device having .vo members formed of bent rods, each rod having one end bent to provide a vertically and a laterally extending open hookand-havin the" other end rebent upon itself to provide an elongated closed. loop in a nori'nally vertical plane the closed. loopvportion's of said rods being loosely connected. to; each other by one loop passing through the other;
